It is Mars' fifth win, and he gave a shout-out to his father. Mars says, "My father, if you're watching this, dad I love you. Look at me pop, I'm at the Grammys right now!"
Mars is having a big night, previously performing his song "Finesse" with Cardi B.
He beat out several other top nominees, including Jay-Z and Kendrick Lamar, for the record of the year honor.
